Fundamental and estimation of thermal contact resistance between polymer matrix composites: A review
TL;DR: The thermal contact resistance between polymer matrix composites (PMCs) imposes the significant impacts on the design, processing and application of these materials as mentioned in this paper , and the main challenges for the accurate estimation are summarized, mainly including the complex interfacial thermal conductance due to the addition of fillers, the anisotropic thermal and mechanical responses due to heterogeneity of PMCs, the uncertain contact mechanics due to special mechanical properties.

Thermal boundary resistance
E. T. Swartz,Robert O. Pohl +1 more
TL;DR: In this article, the thermal boundary resistance at interfaces between helium and solids (Kapitza resistance) and thermal boundary resistances at interfaces interfaces between two solids are discussed for temperatures above 0.1 K. The apparent qualitative differences in the behavior of the boundary resistance in these two types of interfaces can be understood within the context of two limiting models of boundary resistance, the acoustic mismatch model, which assumes no scattering, and the diffuse mismatch model that all phonons incident on the interface will scatter.
